UNITED STATES .ALBERT .AUGUSTUS GUERRA, F LONDON, ENGLAND HAND BLOTTINGnrrLrANcE Application filed October 22, 1930, Serial No. 480,512, and inGreat Britain November r15, 1929.

This invention has reference to hand blotting appliances wherein asurface of blotting paper or similar material is mounted on a rigid basewhich is usually of semi-circular or other curved shape to facilitateuse of the blotting surface in a rocking manner.

The object of the present invention is to enable quick replenishment ofthe blotting surface. Another object is to construct a c blottingappliance wherein a hollow casing is adapted to contain a supply ofblotting material in the form of a movable strip passing out of thecasing and over an operative face thereof7 and then again entering thecasing.

i5 A further object is to provide means for moving the strip over theoperative face as and when required. A still further object is theprovision of means in a blotting appliance of the type described wherebyfresh spools of blotting paper or equivalent may be readily inserted inposition.

With the foregoing and other objects in view the invention consists of acasing in which a strip of blotting material is mounted on a roller orspool and passes out of the casing over an operative surface which maybe flat or curved, thence back into the casing on to a take-up roller orspool, means being provided to rotate one or both rollers or spoolspreferably from the exterior.

The invention may be more particularly understood by reference to theaccompanying drawings in which Fig. l is a perspective view of anapparatus made in accordance with the invention the lid being shownremoved from the casing and inverted.

Fig. 2 is a longitudinal vertical cross section through the apparatusFig. 3 is a longitudinal section through one 0E the spools or rollers 0Fig. 4 is a sectional view of the spindle fitting f Fig. 5 is aperspective view of the complete apparatus.

Referring to the figures, in a preferred form I construct a casing Chaving side members 0 which are connected by a curved member c whichforms or is the basis for the operative face of the blotting apparatus.A lid Z is attached by means of its knob and the screw pin s carried ona bridge piece s Xed between the side members. Carried in the sidemembers and readily revoluble are two spindles Z l upon which may becarried 55 spools or rollers r r adapted to carry rolls b 2') ofblotting paper or any similar blotting material. One or both thespindles may be operated from without the casing by means of a knob suchas c or by a lever or any other well known device.

The curved member c terminates in rolled edges 0 at points slightlybelow the lid Z.

In'operation a strip Z5' of blotting material 65 of any desired kind iswound on to one of the spindles such as r and passes thence over therolled edge of the member c along the operative face of same as shown inFig. 2 and over theopposite rolled edge on to the roller 7". By turningthe knob of either spindle the blotting material may be unwound olf oneroller and wound on to the opposite roller and by the winding processthe blotting surface may be constantly renewed.

Springs Z Z attached preferably to thc lid press down upon the rollededge of the curved member and form with this edge a slot through whichthe blotting strip may pass, the function of these springs being tocreate so sufficient friction on the moving strip to maintain it tautalong the operative surface. The same result may be obtained by theapplication of any convenient friction device applied to any convenientpart of the roller or spindle. If desired a ratchet may be fixed toeither or both the spindles so that they will only be movable in onedesired direction.

The spindles are preferably hollow and are fitted at the ends withspring operated ball im catches t which are adapted to spring intoengagement with the recesses t in the side members and thereby retainthe spindle in its place. Where the spindle is fitted with an operatingknob this is preferably carried on a rod e which passes through thehollow spindle and is screwed into the end thereof as shown at e. Thespindles preferably run in ball bearings e carried in the side membersof the casing.

The spool or roller is operatively connected to the spindle by means ofpins p p xed in the spindle and taking into longitudinal slots p p inthe end of the spool or roller.

It Will be understood that the above de` scription of details ofconstruction represents a preferred form of the invention such as hasbeen found convenient in practice and that the invention is not coniinedto such details of construction but that these may take a variety offorms vvithin the scope of the invention.

I-Iaving now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, I declarethat what I claim is l. A device of the character described comprising acasing inclusive of side Walls and a curved bottom Wall, the ends of thebottom Wall being rolled upon themselves, rolls Within said casing, astrip extending across the o bottom Wall of the casing and over therolled ends thereof into the casing and Wound at its ends on said rolls,whereby dierent portions thereof are adapted to be exposed for use byunwinding the strip from one roll onto the other, a cover for the top ofthe casing, means for fastening the cover to the casing, and resilientmeans carried by the cover for cooperation With the rolled ends of thebottom Wall of the casing to hold taut that portion of the strip whichextends across the bottom Wall of the casing.

2. A device as set forth in claim l in Which the cover carried resilientmeans comprises for cooperation with each of the rolled ends of thecasing bottom Wall a resiliently mounted transversely curved bar ofsubstantially equal length to the Width of the bottom Wall overlying therelated bottom Wall rolled end in parallel relation thereto and With theconvex side of the bar facing the rolled end.

In testimony whereof I have signed my name to this specification.

ALBERT AUGUSTUS GUERRA.
